Definitions

  • the present Invention relates to a technique for improving supporting stiffness of a steering column for securing a steering column to a cab.
  • a steering column is secured to a cab by using a supporting structure as disclosed in New Car Preview "Introduction to NISSAN Atlas F23 series car” (non-patent document 1). Namely, the steering column is secured to the cab through a steering column bracket formed to have channel section and to obliquely rise from a front portion of a cab floor toward a rear side of the vehicle. In order to improve supporting stiffness of the steering column, an upper portion of the steering column bracket is fixedly secured to a member constituting an instrument panel.
  • the non-Patent Document 1 New Car Preview "Introduction to NISSAN Atlas F23 series car", NISSAN MOTORS, CO., LTD, Jan. 1992, p. C-48
  • the present invention has an object thereof to provide a steering column supporting structure capable of improving supporting stiffness of a steering column and reducing vibration occurring at a steering wheel by fixedly securing a middle portion of a steering column bracket to a pedal bracket.
  • a steering column supporting structure wherein an upper portion of a steering column bracket configured to attach a steering column to a cab is secured to a member constituting an instrument panel, and a middle portion of the steering column bracket is secured to a pedal bracket configured to support a pedal.
  • a rotational center shifting apparatus may be provided so as for a rotational center of the steering column in a fore and aft direction of a vehicle to be shifted toward a rear side of the vehicle with respect to an intersection between an axis of a steering shaft disposed under the steering column and the cab floor.
  • the upper portion of the steering column bracket configured to attach the steering column to the cab is secured to a member constituting the instrument panel, and the middle portion thereof is secured to the pedal bracket. Therefore, a total length of the steering column bracket can be shortened, and the middle portion thereof is secured to the pedal bracket which can be strongly Integrated with the cab, so that it is possible to improve attaching stiffness of the steering column bracket to the cab.
  • the supporting stiffness of the steering column can be improved, so that it is possible to greatly reduce vibration occurring at the steering wheel.
  • the steering wheel can follow a trajectory in the movement of a driver's head, so that it is possible to downsize an airbag device attached to the steering wheel.
  • a driver rotationally moves toward the front of the vehicle due to inertia about a seating surface of a seat as a rotational center.
  • the steering wheel rotationally moves toward the front of the vehicle about a rotational center which is shifted toward the rear side of the vehicle with respect to an intersection of an axis of the steering shaft with the cab floor due to deformation of the cab floor. Accordingly, the rotational center of the steering wheel can be closer to the rotational center of the driver and accordingly, it becomes possible to allow the steering wheel to follow the trajectory in the movement of the driver's head.
  • FIG. 1 is an explanatory view for explaining an embodiment of a steering column supporting structure according to the present invention.
  • a steering column 12 which pivotally supports a steering shaft 10 is secured to a cab of a cab-over truck or the like, through a steering column bracket 14 formed to have a channel section.
  • An upper portion of the steering column bracket 14 is fixedly secured through a steering support bracket 16 to a member constituting an instrument panel, for example, an instrument member 18 which extends in a width direction of the vehicle.
  • a middle portion of the steering column bracket 14 is fixedly secured to a pedal bracket 20 which permits suspension of and supports pedals such as an acceleration pedal and a brake pedal in a front portion of the vehicle.
  • a steering wheel 22 is attached to an end of the steering shaft 10 which extends upwards from the steering column 12.
  • the steering shaft 10 which extends downwards from the steering column 12 penetrates a cab floor 24 constituting the cab and is connected to a steering gear box 28 which is disposed under a reinforcing member 26 such as a pipe member configured to reinforce the cab floor.
  • reference numeral 30 denotes a well-known tilt mechanism for adjusting a tilt angle of the steering wheel 22 depending on a body size or the like of a driver.
  • a rotational center shifting apparatus which allows the rotational center of the steering column in respect of the fore and aft direction of the vehicle to be shifted toward the rear side of the vehicle with respect to an intersection of an axis of the steering shaft disposed under the steering column with the cab floor.
  • FIG. 2 is an explanatory view for explaining a rotational center shifting apparatus according to a first embodiment of the present invention.
  • a steering support link 34 (rotating member) which can rotate about a rotational axis extending in the width direction of the vehicle is fixed to a portion which is located in the rear side of the vehicle with respect to an intersection 32 between an axis of the steering shaft 10 below the steering column 12 and the cab floor 24.
  • a lower end of the steering column 12 is connected to another portion of the steering support link 34 rather than the rotational axis thereof via a steering support rod 36 which extends downwards along the steering shaft 10.
  • the upper and lower ends of the steering support rod 36 are fixed to the steering column 12 and the steering support link 34, respectively, in a mutually rotatable manner.
  • the steering column 12 when the steering wheel 22 rotationally moves toward the front of the vehicle along with the occurrence of frontal collision of the vehicle, movement of the steering column 12 can be restricted by the steering support rod 36, and the steering column 12 carries out a rotational movement about an axis of rotational of the steering support link 34 toward the front of the vehicle. Accordingly, as shown in the drawing figure, the rotational center of the steering column 12, that is, the rotational center of the steering wheel 22 is shifted from a position C 1 to a position C 2 and the trajectory thereof is changed from a trajectory A to a trajectory B.
  • the rotational center of the steering wheel 22 becomes closer to the rotational center of the driver, so that it is possible to allow the steering wheel 22 to follow a trajectory C in the movement of a head 40A. Accordingly, the head 40A can be received in the central portion of the airbag 42. As a result, even if the airbag 42 is not expanded in a size larger than the diameter of the steering wheel 22, the safety for the driver 40 can be secured. In addition, due to the smaller-stzed airbag, it is possible to achieve curtailment of the cost while reducing the weight of the vehicle, and so on.
  • FIG. 3 is an explanatory view for explaining a rotational center shifting apparatus according to a second embodiment of the present Invention.
  • an auxiliary steering support rod 44 is provided.
  • One end of the auxiliary steering support rod 44 is fixed to a portion of the reinforcing member 26 which portion is located in the front side of the vehicle with respect to the intersection 32, and the other end thereof is secured to the steering support link 34. More specifically, the other end of the auxiliary steering support rod 44 is fixed to such a position that, when the auxiliary steering support rod 44 moves toward the rear side of the vehicle due to deformation of the reinforcing member 26. the steering support link 34 can be rotated in the direction in which the steering support rod 36 is pulled downwards.
  • auxiliary steering support rod 44 Is disposed to extend in the fore and aft direction of the vehicle along the reinforcing member 26, and both ends thereof are fixedly secured to the reinforcing member 26 and the steering support link 34, respectively, in a mutually rotatable manner.
  • FIG. 4 is an explanatory view for explaining a rotational center shifting apparatus according to a third embodiment of the present invention.
  • a lower portion of the steering column 12 is connected via a steering support wire 46 to an upper surface of the cab floor 24 which is located in the rear side of the vehicle with respect to the intersection 32.
  • movement of the steering column 12 can be restricted by the steering support wire 46, and the steering column 12 rotationally moves toward the front of the vehicle about a connection portion of the steering support wire 46 connected to the cab floor 24, as a rotating center.
  • the rotational center of the steering column 12 that is, the rotational center of the steering wheel 22 is shifted from a position C 1 to a position C 2 and the trajectory thereof is changed from a trajectory A to a trajectory B.
  • the steering wheel 22 can follow the trajectory of the driver's head.
